A cyclocomputer is a device mounted on a bicycle that calculates and displays trip information, similar to the instruments in the dashboard of a car.
A basic cyclocomputer may display the current speed, maximum speed, trip distance, trip time, total distance traveled, and the current time.
More advanced models also may display altitude, incline (inclinometer), and temperature as well as offer additional functions such as average speed, pedaling cadence, and a stopwatch.
